On the VM running Apache Brooklyn, it is recommended that nproc and nofile are reasonably high
(e.g. 16384 or higher; a value of 1024 is often the default).
+## For Centos 7
+To check the current limits, you will need to know the PID for the brooklyn process. You can find
+this by running `systemctl status brooklyn` and checking the `Main PID` line.
+
+To see the current limits, run `cat /proc/<brooklyn PID>/limits` replacing <brooklyn PID> with the Main PID
+from above
+
+To override the default limits, you will need to create a `limits.conf` and populate it with the required
+values as follows:
+
+```
+mkdir -p /etc/systemd/system/brooklyn.service.d
+
+cat > /etc/systemd/system/brooklyn.service.d/limits.conf << EOF
+[Service]
+LimitNOFILE=16384
+LimitNPROC=16384
+EOF
+```
+
+You will then need to reload the systemctl daemon and restart brooklyn:
+
+```
+systemctl daemon-reload
+systemctl restart brooklyn
+```
+
+To check the new limits, you will need to obtain the new brooklyn PID by running `systemctl status brooklyn`
+and `cat`ing the process limits as above
+
+
+## For Centos 6
+Please check the limit for opened files `cat /proc/sys/fs/file-max` and increase it.
+You can increase the maximum limit of opened files by setting `fs.file-max` in `/etc/sysctl.conf`.
+and then running `sudo sysctl -p` to apply the changes.
+
If you want to check the current limits run `ulimit -a`. Alternatively, if Brooklyn is run as a
different user (e.g. with user name "brooklyn"), then instead run `ulimit -a -u brooklyn`.
